(12) Minimum stroke adjustment
Use the control knob to match the stroke with the scale, adjusting the stroke
to 1mm.
①
Loosen the lock screw on the control knob (do not loosen the lock screw of
the control nut), then turn the control knob to the left by the amount of the
difference between the stroke and the minimum graduation (mm).
(
※
one turn = 0.8mm, the screw pitch of the T valve push rod and the control
knob is 0.8mm)
②
Loosen the lock screw of the control nut and turn the control knob to the
right until it stops. Tighten the lock screw again. (See Figure 8-14)

compressed air, so don’t push or hold the mandrel by hands or similar.
Turning mandrel may hurt hands or similar.
8-8. Hydraulic Oil filling
If the stroke gets too short due to a lack of hydraulic oil (if a proper caulk
stroke is impossible, even after stroke adjustment), follow the procedure
below to fill up the hydraulic oil.
If the stroke again becomes inadequate immediately after you filling up
with oil, the oil seal must be replaced. Send the tool for repair.
